District/Circle: Mark Lane—Tower Hill—Aldgate South, this is a smooth arc.

Northern Line Charing Cross Branch: Kennington—Waterloo: northbound is a straighter line, passing closer/under the Imperial War Museum, not Kennington Road. Should be able to peg it from the MTV next to the cafe

Bakerloo: London Road Depot: which spur is the tunnel and which is the headshunt?
